TGV INOUI Launches Brussels-Basel Weekend Pilot in July 2027

BRUSSELS / LUXEMBOURG – A new weekend-only TGV INOUI pilot will connect Brussels with Strasbourg and Basel from July 2027, stopping at Paris Charles de Gaulle Airport but omitting Luxembourg. The service will run three days a week, departing Brussels around 07:00 and reaching Basel around 12:30, a journey of roughly five and a half hours. Tickets are expected to go on sale in spring 2027, while Luxembourg’s transport minister says her ministry was not involved in the project’s preparation.

What Is the Full Scope of This Project?

The planned service will operate one round trip per day on Fridays, Saturdays and Sundays using TGV INOUI rolling stock, with stops at Brussels, Paris Charles de Gaulle Airport, Strasbourg and Basel. The return train will depart Basel around 14:00 and arrive in Brussels around 19:00. The pilot will use existing high-speed infrastructure in France, avoiding a detour through Luxembourg, and will operate on a commercial basis without dedicated public subsidies, according to the Luxembourg Ministry of Transportation. Luxembourg Green MP Meris Šehović has asked the government for an explanation, citing the former direct Brussels–Basel rail link that passed through Luxembourg.

Key Project Data

How Does This Compare to Similar Projects?

The new Brussels–Basel pilot uses existing French high-speed infrastructure, unlike the Karlsruhe–Basel high-speed railway, which has a planned length of 182 km and has been under construction since 1987 with completion projected between 1993 and 2031 (Source: Wikipedia, 2025). Belgium completed ETCS Level 2 installation across 2,274 km of national rail network by December 2025 to support cross-border interoperability, which could lower operational barriers for services like this one (Source: RailwayPRO, 2025). At the EU level, Luxembourg was one of five capitals missing from the European Commission’s 2040 high-speed rail vision, alongside Helsinki, Dublin, Nicosia and Valletta (Source: Railmarket, 2025). No total project value, capacity per train, revenue-sharing model or ticket pricing was disclosed at announcement.

Editor’s Analysis

The pilot fits a pattern of commercially funded, weekend-only cross-border high-speed services using existing infrastructure to test demand before committing to regular frequency. It also follows broader growth in cross-border rail, with Eurostar carrying 20 million passengers in 2025 (Source: RailwayPRO, 2025). Luxembourg’s exclusion shows that small-state connectivity remains dependent on neighbouring operators’ route choices rather than EU corridor ambitions (Source: Railmarket, 2025).
